Hi Kerneels,
I think that I remember the Python Style Guide saying to use as few blank lines 
as necessary. I'm paraphrasing, here. Probably badly, too. I'll check again.

I've also had this annoying blank line problem a lot before. Don't know
why it can't be fixed in the Python interpreter / compiler?? I mean,
it's a simple thing.

These days I don't leave any blank lines unless it's really the end of a
block.

In defense of Python I  would like to site NVDA. High performance areas
are coded in C++ but where a more dynamic approach is required it's all
Python. NVDA performs really well in my opinion, and it just gets better
each new release.
